Primer pair rs1835740PyroF/rs1835740PyroR-BIO and rs4354668PyroF-BIO/rs4354668PyroR were used to generate biotinylated PCR products flanking SNPs rs1835740 and rs4354668, respectively. Primers rs1835740PyroSeq and rs4354668PyroSeq were used for pyrosequencing. The target sequence and the order of nucleotide dispensation for each pyrosequencing assay are listed. In the dispensation order the nucleotides used as negative controls for pyrosequencing are underlined. In optimal pyrosequencing conditions these nucleotides are not incorporated into the target DNA sequence and thus their addition do not generate peak on the pyrogram (see also Figure 2). The nucleotide change in the target sequence is indicated in bold.
